SPECIFICATION forming part of Letters Patent No. 352,960, datedNovember'23, 1886.

7 Application filed J uly 3, 1886. Serial No. 207,069. (No model.)

clare that the following is a full, clear, and ex act description of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to theletters and figures of reference mark'edthereomin which-- Figure 1 is a perspective view of my improvedstraw-cutter, parts being broken away.

Fig. 2 is a detached view of the cutter-bar.

Figs. 3 are detached views of the main shaft, showing one of the rotaryarms attached thereto and the knives placed in position, to be properlyattached to-said rotary arm. Fig. 4 is a detached view of a portion ofthe lower feed-shaft, showing three sections of thefeedrollers locatedthereon. Fig. 5 is a detached view of a portion of the upperfeed-shaft,showing a section of a feed-roller located thereon. Fig. 6 isa detached view of the bracket and pin for changing the speed of therollers. Fig. 7 is a top view of a portion of the cutter-bar and one ofthe rotary arms properly located on the main shaft.

The presentinvention has relation to foddercut-ters; and it consists inthe different parts and combinations of parts hereinafter described, andparticularly pointed out in the claims.

Similar letters of reference indicate corresp onding parts in all thefigures of the drawings.

A represents the frame, which may be substantially of the form shown inFig. 1, and, as shown,is properly braced,so as to rigidly hold the same.

To the front or forward end of the frame A are securely attached theplates or bars a, said plates or bars being provided with suitablebearings for the main shaft B, said shaft B being located substantiallyas shown in Fig. 1.

To this main shaft B are attached the rotary placed in the positionshown in Figs. 3, and for the purpose of securely holding the rotaryarms C.

At agiven place on the main shaft B the set-screws c are provided, asshown in the drawings. 'To the ends of the rotary arms 0 are adjustablyattached the knives D. Said knives are substantially of the form shownin the drawings, and are securely attached to the rotary arms 0 by meansof the clamping-bolts d, or their equivalents. For the purpose ofadjusting the knives Him or out from the main shaft B the slots e areprovided, as shown in the drawings. of the form shown, and, as shown,are provided with the shanks D, which are integral with the knives D,the knives D being at an angle to the shanks, and when properly attachedto the rotary arms 0 will be at an angle to said arms. The rotary arms 0are placed spirally ,on the main shaft B, as shown in Fig. 1. The

The knives D are substantially object and purpose of so placing therotary arms 0 are that but one knife will cut at any one time, therebycausing the fodder to be out much easier. I

The cutter-bar E is substantially of the form shown in Figs. 1, 2, and7, and is securely held in proper position by means of clamping-bolts ortheir equivalents. I prefer to attach the cutter-bar to the plates orbars at This cutterbar E is provided with diagonally-arranged teethf,which are formed integral with the bar E. The teeth f are so adjustedthat their side faces will be in line with the knives D when said knivespass between them. The knives D are placed upon opposite sides of therotary two knives upon one of the, rotary arms will pass between two ofthe teeth f.

It will be seen that by means of the setscrews 0', Iam enabled to adjustthe knives D to or from the teeth f, and thereby regulate the cutter-barandknives for different kinds of fodder. To one end of the shaft Bisrigidly attached the pinion F, which meshes into the wheel G.

To the side of the'wheel G is attached or placed the pinion g. Thispinion g may be formed integral with the wheel G, or it may be formedseparate and attached in .any we1larms 0, as illustrated in Figs. 3, sothat the IOO known manner. The pinion g communicates motion to the wheelH, which isrigidly attached to the lower feed-roller shaft, as shown inFig. 1, motion being communicated to the upper feed-roller shaft bymeans of ordinary finger gear-wheels. The wheel G and pinion g aremounted on a stud or pin, K, projecting from one end of a bracket, L,having a slot, M, for passage of a screw by which it can be adjustablyattached to the machine-frame.

The feed-rollers I are formed in sections and strung on the shafts, asshown in Figs. 1, 4:, and 5. The rollers I, designed and calculated forthe lower shaft, are fluted or corrugated, as shown in the drawings. Therollers designed and calculated for the upper shaft are provided withthe cleats J, which are located substan tially as shown.

It Will be seen that by forming the feedrollers I in sections machinesof different widths can be made by increasing or decreasing the numberof sections. It will be understood that the feed-rollers proper shouldbe pressed against each other by means of springs.

For the purpose of changing the speed of the feed-rollers I, the pinion9 may be formed of different diameters and adjusted to the wheel H bymoving the pin K, on which the pinion 9 turns, to or from the wheel H.For

this purpose the pinion g is preferably made separate from the wheel G,but capable of being secured thereto in any suitable manner.

' Having now fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is v 1. The combination, with thediagonallytoothed cutter-bar E, of the rotary shaft B, the arms 0,connected in pairs by collars and adjustably secured to said shaft indifferent plane's, thereby forming a spiral thereon, and the knives D,adjustably secured to the ends of said arms with their cutting-edgesstanding at an .angle thereto, substantially as described.

2. The combination of the feed-rollers I, the toothed cutter-bar E, therotary shaft B, having pinion F, the arms 0, mounted on said shaft andprovided with knives-D, the adjustable bracket L, having slot M and studK,the wheel G and pinion g, mounted on said stud, and the wheel H,attached to the lower feedroller, substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
